STRUCTURE A structure is a collection of variable which can be same or different types. You can refer to a structure as a single variable, and to its parts as members of that variable by using the dot (.) operator. The power of structures lies in the fact that once defined, the structure name becomes a user-defined data type and may be used the same way as other built-in data types, such as int, double, char. struct STUDENT { int rollno, age; char name[80]; float marks; }; int main() { STUDENT s1, s3; // declare two variables of the new type cin >> s1.rollno >> s1.age >> s1.name >> s1.marks; cout
